|

| 4 | <para><acronym>KDE</acronym> is a comprehensive desktop environment that builds on
|
|---|
| 5 | <application>X</application> Window System and <application>Qt</application> to provide
|
|---|
| 6 | a window manager and many user tools, including a browser, word processor,
|
|---|
| 7 | spreadsheet, presentation package, games, and numerous other utilities. It
|
|---|
| 8 | provides extensive capabilities for customization.</para>
|
|---|
| 9 |
|
|---|
| 10 | <para>The <acronym>KDE</acronym> instructions are divided into two parts. The first part, the
|
|---|
| 11 | core packages, are needed for the rest of <acronym>KDE</acronym> to work. The second part
|
|---|
| 12 | presents additional packages which provide functionality in various areas
|
|---|
| 13 | (multimedia, graphics, etc.).</para>
|
|---|
| 14 |
|
|---|
| 15 | <para>There are two alternatives for installing <acronym>KDE</acronym>. Option one, that
|
|---|
| 16 | is used by most of the commercial distributions, is to
|
|---|
| 17 | install <acronym>KDE</acronym> in the standard system prefix: <filename>/usr</filename>.
|
|---|
| 18 | This option allows the use of KDE without the need for any additional configuration such
|
|---|
| 19 | as modification of various environment variables or configuration files. Option two is
|
|---|
| 20 | to install it in a unique prefix such as <filename>/opt/kde</filename> or
|
|---|
| 21 | <filename>/opt/kde-&kde-version;</filename>. This option allows for easy removal of
|
|---|
| 22 | the package.</para>
|
|---|
| 23 |
|
|---|
| 24 | <tip>
|
|---|
| 25 | <para>All the <acronym>KDE</acronym> packages are comprised of various components.
|
|---|
| 26 | The default is to
|
|---|
| 27 | install most of the components. If specific components are to be eliminated, the
|
|---|
| 28 | official way is to set the variable <envar>DO_NOT_COMPILE</envar>.
|
|---|
| 29 | This comes in handy when there are problems compiling a particular
|
|---|
| 30 | component.</para>
|
|---|
| 31 |
|
|---|
| 32 | <screen><userinput><command>DO_NOT_COMPILE="component1 component2" \
|
|---|
| 33 | ./configure --prefix=&kde-dir; ...</command></userinput></screen>
|
|---|
| 34 |
|
|---|
| 35 | <para>The core <acronym>KDE</acronym> packages also honor this variable, but omitting components
|
|---|
| 36 | from the core packages is not advisable since it may result in an
|
|---|
| 37 | incomplete <acronym>KDE</acronym> installation.</para>
|
|---|
| 38 | </tip>
|
|---|
| 39 |
|
|---|
| 40 | <note><para>In each of the packages,
|
|---|
| 41 | one other option to <command>configure</command> can be added:
|
|---|
| 42 | <parameter>--enable-final</parameter>. This option can speed up the build
|
|---|
| 43 | process, but requires a lot of memory. If you have less than 256MB of RAM,
|
|---|
| 44 | this option may cause swapping and significantly slow compilation.</para></note>
